Some emails are worth keeping or at least savoring beyond a quick stroke of the delete key. And yesterday one of my pals, Renae Martin, keeper and writer of Expedia Corporate Travel email travel alerts, came across an update warning travelers of hooligan violence. And while the alert was interesting in itself (Do we even have hooligans in the U.S.?), Renae made it my most memorable email of the week:

Renae writes... "So I'm really interested in this hooligan violence. From reading your last blog I thought you'd like to know about Hungarian hooligans. Not only is alliteration at work, but these hooligans are apparently organizing, as opposed to non-alliterative hooligans who tend toward anarchy. Hooligan sounds like it's one step above mischief maker. What do we call hooligans in the U.S.? Criminals? Also, don't these two countries Bosnia and Herzegovina-Croatia have some kind of a UN restraining order?
 

The following five matches have elevated potential for hooligan violence:

England-Germany
Time: 2000
Location: Wembley Stadium, London
Authorities are effective in preventing hooliganism, but violent unrest near the stadium, especially after the game, is possible. Avoid Wembley Stadium and nearby public transportation between 2200-2400 Aug. 22.

Hungary-Italy

Avoid the area near the stadium and Andrassy Avenue between Hero's Square and Octogon before and after the match; avoid the M2 (Red) Line between Deak Ferenc ter and Ors Vezer tere unless going as far as Keleti Station. Also, avoid the M1 (Yellow) Line between Deak Ferenc ter and Mexikoi ut.
